1 N 'PIPE BEAMER.

Application filed Septemeer To all whom t may, concern:

Be it-known that I, HENRY `KrimisHELD,`

' a citizen of the United States, anda resident i simple, compact, durable `and `,streng pipe `reamer which is adaptedto be collapsed4 ofNewark, in the county oli- Essex andv State of New Jersey, have inventeda new and Improved Pipe Beamer, of? which the followingV is a t'ull,clear,and exact description. `This invention relates toa new andimproved pipe reamer, especially.` adapted vfor tobacco pipes. .i l l vY An ob'ect of the inventionrsjto providefa pended onakey ring. r5

lnother object concernsthe;.provision of a pipefreamerwhich canbesuspeniled on a keyringand atfthe same 'time be quickly and easilyextended intosoperativeposition for the purpose oi'reaming out `a pipe,.preferablya tobacco pipe, although other tubular 4articles can bereanied therewith.

A further object concerns the provision when not in use so `that it canreadily snsf of means whereby the device'can be made of simple,inexpensive material, preferably sheet metal, and so as to occupy a verysmall space when not in use. f

The invention is illustrated in the drawings, of which- Figure l is asection through the bowl of` a pipe showing'the reamer in position;

Fig. 2 is a perspective View showing the' reamer in its collapsed closedposition;

- Fig. 3 is a perspective view of the reamer showing it in open oroperative position;

Fig. 4 is a section taken on the line 4;-4 of FigoQ; and V- Fig. -5 is asection of Fig.` 3. Y

.The form of the invention shown in the drawings is a preferred form,although it is understood that modifications inthe contaken on the line5-5 struction and arrangement of the parts and Vin the character of thematerials used may be adopted without departing from the spirit of theinvention as set forth in the appended claims.

In its genera-l aspect the invention comi prises two metal plates theedgesro'f which are formed to conform to theproiile of the bowl of. apipe, preferably Va tobacco pipe;-k

These edges are curved and sharpened 'and act as :cutting edges. `Theseplates are slotted and are so disposed with respect to each other as tobe movable one with respect to the other but are not ordinarily comlwith two `wing portions.

each. other, whereas when vnot in operation `they .Kareladapted to beswung relative -toeacli other to lie ilat against each other. Asim- -ple`little `latch is provideduon one of the .plates'to be moved intoposition to grip both of the `plates and hold them in :their closedposition@ These plates are `provided with :slots inorder to permit theirbeing swung flat, against each other without'd'i-sengagement andI arenecessarily provided with por# tions offset with respect to each otherso that the pivotal place u .Y l g -The particular form of l-theinvention swinging `movenient can talle pletely disengageable. vTheirnormal posi i tion when `1n `operation 1s ati-ight angles to i whichconstitutesthe preferred embodiment i thereof-fis.shown in thedrfawingsand Vis adapted fto be Vused `to reamaout the bowl la of a pfp,e,..asshownfin Fig The .reamer preferably constitutes thertwo "plat-es A andB. These plates are formed-l of wing ,por-

tion-s 1, 2, 3 and 4 each plate being provided One wing portion of `aplate is offset with respect to the other wing portion, Vtherebyproviding a sort ofn y shoulder 5, asshown in Fig. 4L. Each plate isprovided with this sort of shoulder. The plate A is provided with a slot6. -The plate B is-provided with Vtwo slots 7 andV 8,v the `slot v7being closed at both ends butthe slot 8 being openat 4thebottom or lowerend -o the plate B. In the manufacture of the devicefthe plate B is cutorjslit between the tWo slots therein and Vseparated far enough topermit the plate' A tojbe slipped into po- Thereafter this slitisp-sealed by separated edges and confine the plate A into permanentplateB. Y

A latch member`9 is mounted on oneolf the plates such as B and adaptedwhen swung downto engage withone of the -wings v of the plate A whensaid plate is swung into a position flat against plate B. The slot 7pivotal engagement with thev extends well up into the plate B and its yupper end lies above ashoulder `or enlarged portion 10 torrnedv thereonso that the plate A as' itis swung into operative position is moved upinto thez upper end of slot `7` so` that'its upperfface `lies againstthis portion Vof ythefplate B. This provides a certain amount ofrigidity tothe plate. Y Normally,

to place thexparts in their closed' position the plate A is allowedtodropa bit until its upper edge is below the shoulder l0, and then isswungaround flat against the plate B and locked. In this lockedpositionl it will be seen that the lower edge 11 of the 1 plate A liesbelow the lower edge of the plate B but that normally when they are intheir operative relation, as shown in Fig. 3, their lower edges areatthe same level. The upper portion of the plate B may be provided with akey-head or plate l2 adapting the device to be mounted or suspended troma key ring if desired. y

This device, therefore is adapted for ready suspension on a key ring andcan be quickly and easily placed in operative condition for use inreaming the bowl ot a pipe. 'It is to be clearly understood that thisreaming device can be used for other things-'besides tobacco pipes andit is not my intention to limit it to this use. Y

What I claim is:- Y l. A pipe reamer, which comprises a pair ofpivotally movable plates adapted in one position to be disposed at anangle to each other for reaming purposes `andato be disposed iiatagainst each other when not in use. 2. A pipe reamer, which comprises apair 0f pivotally movable plates adapted in one position to bedisposedat an angleto each other for reaming purposes and to be disposed fiatagainst each otherwhennot in use, and means on one of said plates toengage with the other to lock the plates in their closed position.

3. A pipe reamer, which comprises a. pair of pivotally engageablecollapsible plates adapted to be disposed at an angle t0 each other whenin use and collapsed against each other when not in use.

4. A pipe reamer, which comprises a pair of plates having slots therein,the slotted port-ions on one plate adapted to pass through the slots inthe' other, each plate being offset in line with the slots to permit oneplate to be swung Hat against the other.

5. Apipe reamer which comprises a plate having slots therein, shouldersat the upper end of this plate on opposite sides thereof adjacent theupper yend ot one of said slots, a second plate hav-ing a slot embracingthe unslotted portion of the irst-mentioned plate, said plates havingoffset portions in Y line with the slots to permit them to be swung flatagainst each other, said second plate adapted to be swung at an angle tothe first plate and moved into engagement with the shoulders whereby itcan be maintained substantially in this angular position Vduring use,said second plate adapted to be dropped down into the slots of the otherplate prior to being swung fiat thereagainst.
